Tramp is very tenacious in overriding the PATH setting of a remote machine. How can I completely disable this, so that Tramp's PATH is identical to what I get when I manually log in with ssh on the terminal?

The ~/.bashrc in my remote machine looks as follows:

export PATH1=$PATH
# activate some Python virtualenvs, etc...
export PATH2=$PATH

I want the final PATH to be PATH2. The closest I can get to that is when setting tramp-remote-path to the value '(tramp-own-remote-path), in which case my PATH ends up being identical to PATH1. (I'm checking this by doing M-x compile RET env RET while editing a remote file.)

One interesting solution (with other applications as well) would be to stipulate, as a directory or connection-local variable, an additional rc file on the remote machine that is sourced every time Tramp connects. Is this possible at all?

Short solution: add all PATH-related settings to ~/.profile instead of ~/.bashrc, and make sure the former is sh-compatible.

Interesting idea. I have added it to the TODO list of Tramp. If you want to discuss further, I invite you to the <[email protected]> mailing list. SX is not intended for longer discussions.

  • Do you consider this just a bug, or would you like more details about my motivation here? In the latter case, I'd be happy to discuss it on the mailing list.

  • Tramp's path-munging was killing my ability to use M-x compile to build anything on the remote machine because it was nuking the path to gcc etc (I use devtoolset-n on CentOS to get gcc-n for different versions). My sledgehammer approach in emacs-27.2 was to put this in my .emacs - (eval-after-load "tramp-sh" '(defun tramp-set-remote-path(vec))) - BOOM!
